# Concat vs warp

Concat and warp share 13 technologies: objc2-app-kit, objc2-foundation, Tokio, fontdb, wgpu, objc2-metal, objc2-quartz-core, ort, tokenizers, image, resvg, schemars, and log. Both are written in Rust.

- [jub0t/Concat](https://seerepo.com/r/jub0t/Concat): Beta: The truly free, open-source, local-first, cross-platform video editor. Scriptable through a JSON-RPC API & MCP.
- [warpdotdev/warp](https://seerepo.com/r/warpdotdev/warp): Warp is an agentic development environment, born out of the terminal.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
